Forgot encryption password

#1 Post by Scooby »

:cry: :cry: a couple of months back I encrypted an archive with aes

now I forgot the password

had a 40 min guessing session yesterday but couldnt
get the right one.

I wonder if the file was corrupted, got to start authenticate with hmac also.

maybe I should buy some ginko-biloba to refresh my memory.

maybe I should ask NSA for help

Can make the "password" of a file an MD5 of File-name plus salt , e.g. ...

File-name is "Bank_Statement_150714".
Salt is "ThisIsTopSecretStuff".
Password is MD5(Bank_Statement_150714ThisIsTopSecretStuff)
=> 40eec9a46556dad99a4d6d23a9a2b068

You only ever have to remember one thing : the salt,
( each "password" will be a different 32-character hexadecimal number ).
Preferably don't make the salt from dictionary words , maybe use another MD5.

For extra layers of tin-foil iterate.
